SPECIFICATION forming part of Letters Patent No 634,624, dated October 10, 1899, Application filed July 8,1899. Serial No. 728,138. (No model.)

To all whom, it may concern:

Be it known that we, LOUIS LEMIEUX and Lows IIAAS, citizens of the United States, residing at New York, county and State of New York, have invented certain new and useful Improvements in Pivot Attachments for Pedal Members, of which the following is a full, clear, and exact description.

Our invention relates to an improved pivot IO attachment for pedal members of pianos, organs, 820.; and our object is to provide an attachment which may be easily put in place, will take up only a small amount of room, and in which the pivots can be adjusted by the insertion of a wire in the head of a screw to turn the same, in this way doing away with nuts and the consequent necessity for the use of wrenches, which require space for manipulation.

In the preferred embodiment of our invention shown in the drawings, Figure 1 represents a plan view of our improvement; Fig. 2, a side elevation; Fig. 3, a modification.

In the above preferred embodiment, A represents a portion of a piano.

B represents the base of our attachment, which, as shown in this embodiment, is provided with screw-holes, through which pass screws O for fastening it in place. This base is preferably constructed of some metal, such as iron or brass, and has bent up from opposite sides of it wings D D, so that their flat faces oppose each other. These wings are flexible and preferably slightly resilient and are provided with perforations in line with each other, one of which perforations is screwthreaded, and through said perforation passes an adjusting-screw H, the screw-threaded portion of which engages with the screwthreaded perforation in one of the wings.

The head of this screw has one or more perforations therethrough transverse of the axis thereof, so that a wire can be inserted therein and the screw turned thereby without the necessity of using a wrench. To provide a pivot for the pedal member G, we preferably punch inward by means of a die the pivotpoints F F, which project inwardly from the faces of the wings, are located between the base and the perforations, and hold between them the pedal member G. In Fig. 3 we have shown these pivot-points as consisting of separate pieces, which may be screwed into holes in the wings or otherwise fastened thereto.

Economy of space in a piano or organ is important, as well as ease of attachment and detachment of the parts. Vith our pedal attachm cut the only tools necessary are a screwdriver and a piece of wire, the manipulation of both of which takes up only a small space compared with that which is necessary when a wrench is used. The screw H may be adjusted very quickly and the pedal member Gr taken out without disturbing the base and without the necessity of removing any nuts or other parts.

It will be obvious that many changes may be made in the disclosure herein without departing from the spirit of our invention.

What we claim is 7o 1. In a device of the character described in combination, a base having holes for the insertion of fastening-screws, a pair of flexible wings extending from opposite sides of said base, said wings having perforations in line with each other, one of the same being screw-threaded, a pivot-point on each wing between the base and the perforation in that wing, said points extending inwardly toward each other, a pedal member held between said pivot-points, and a screw passing through both perforations and engaging said screwthrcaded perforation, said screw having a head and a perforation therein transversely of the axis thereof adapted to receive a wire 8 5 to turn the same to draw said wings toward each other.

2. In a device of the character described in combination, a base having holes for the insertion of fastening-screws, a pair of flexi- 9o ble metallic wings integral with and bent up from opposite sides of said base and lying adjacent one another but leaving a space be tween the same, said wings having perforations in line with each other, one of the same being screw-threaded, a pivot-point on each wing between the base and the perforation in that wing, said points being formed by punching inwardly the metal of the wings and said points extending toward each other, a pedalv IOO member held between said pivot-points, and I Signed at New York city, New York, this a screw passing through both perforations 3d day of July, 1890.

thereof adapted to receive a Wire to turn the same to draw said Wings toward each other.
